Review Questions
How did Jefferson's vision for America influence his approach to territorial expansion during his presidency?
Jefferson's vision for America was rooted in the belief that a nation of independent farmers was essential for a healthy democracy. His approach to territorial expansion was motivated by this vision, leading him to support the Louisiana Purchase as a means to provide ample land for agricultural development. He believed that expanding westward would not only secure land for future generations but also promote economic self-sufficiency and strengthen democratic values.
Discuss the implications of the Louisiana Purchase on U.S. foreign relations in the early 19th century.
The Louisiana Purchase had significant implications for U.S. foreign relations by asserting American sovereignty over a vast territory and enhancing its geopolitical position. By acquiring this land from France, the U.S. effectively removed a major European power from its western frontier, which reduced potential threats. Additionally, it set a precedent for future acquisitions and demonstrated a willingness to engage in diplomatic negotiations, thereby establishing America as an emerging power on the global stage.

The territorial expansion initiated during Jefferson's presidency had profound long-term effects on American society and politics. It contributed to a sense of national identity and unity as Americans began to envision their nation extending across the continent.
